I'm using Windows 7, and the latest version of NVIDIA display driver I can install on my computer is 275.33 (or 266.58, I can't decide now, see below).
When installing newer version of the driver (e.g. 275.50 and 280.26), the installer always fails at "Installing NVIDIA Control Panel", then Windows 7 reverts to 275.33 (the newest stock version?).
I tried to find installation logs but couldn't find it. I tried to completely delete (in fact I renamed)
c:\progra~1\nvidia~1 folder but still couldn't install.
How to resolve this problem? Any help is appreciated.
